Read the full NTSB narrative

THE PILOT REPORTED A LOSS OF ENGINE POWER DURING AERIAL APPLICATION MANEUVERS AND WAS FORCED TO LAND IN A SOYBEAN FIELD. DURING LANDING ROLL, THE PILOT INITIATED AN INTENTIONAL GROUND LOOP TO AVOID A RESIDENCE AT THE END OF THE FIELD, WHICH RESULTED IN THE COLLAPSE OF THE MAIN LANDING GEAR AND SUBSTANTIAL DAMAGE TO THE AIRPLANE. EXAMINATION OF THE ENGINE REVEALED A BROKEN CRANKSHAFT, A BROKEN MAIN CRANKSHAFT BEARING SHELL, AND EVIDENCE OF RUBBING BETWEEN THE CRANKCASE PARTING SUFACES DUE TO INSUFFICIENT TORQUE BEING PLACED ON THE CRANKCASE THROUGH BOLTS.
